Can nokia6670 send short messages in groups?

Well, there is no grouping function. However, there is a simple way to delete emails, that is, go into the inbox, click options, and then mark and mark all emails. At this time, all messages will be ticked, and then click the option to mark and unmark the message you want to keep, so that the tick in front of this message will be gone. Then when you click "Delete", all the selected messages will be deleted, and all the unselected messages will be kept.
